The 27 May 2026 build (13855) is out.
luisalberto:
Goto to Settings -> Environments Select Colours and over the OK and Cancel Buttons You will see the combo Box to change the theme. I am using Windows 11 25 H2. See the attach Image file. I dont like the dark mode and I use Light mode in Codeblocks.

Effectively, I forgot to mention this as a third solution, introduced quite recently.
Nevertheless, the 2nd solution may be applied to many wxwidgets softwares where darkmode is not explicitely implemented.

A debugging check in this application has failed.

I've found that deleting the .conf file just one time solved this for me.

Pecan, trying to re-customize my default.conf I think I found the root cause of the issue and so a quick way to fix it. The root cause of the debugging checks is a specific setting
Settings->Environment Settings->Notebooks Appearance->Tab Style
If you set the tab style to Firefox2 or Microsoft Visual Studio 7.1 the debugging checks are raised
Uisng default or Simple Tabs no debugging checks are raised.
So to me is enough to change my old settings from Firefox 2 to default to get a working default.conf (my old one). I hope this helps to understand how to fix the issue.

This didn't work for me (I'm experiencing the same problem), as my tabs were set to default already

Hello Developers.
Unfortunately the folding margin is located next to the text inside the editor and thus, it happens very easily that you force a folding even you just want click at the first line position, what is very annoying.
While reviewing the current margin configuration in cbEditor.cpp, I noticed that Code::Blocks defines its own margin IDs:
--- Code: ---#define C_LINE_MARGIN 0
#define C_MARKER_MARGIN 1
#define C_CHANGEBAR_MARGIN 2
#define C_FOLDING_MARGIN 3
--- End code ---
As far as I understand it, Scintilla (and wxScintilla) always render margins strictly in ascending ID order.
Because of this, the folding margin (ID 3) appears directly next to the text area in the editor. This placement makes it easy to accidentally trigger fold/unfold actions when clicking near column 1, especially on high‑resolution displays.
Other Scintilla‑based editors (SciTE, Geany, Notepad++) avoid this issue by placing the folding margin immediately to the right of the line‑number margin. This provides a natural buffer zone and significantly reduces accidental folding.
In Code::Blocks, the folding margin is configured here:
--- Code: ---control->SetMarginType(C_FOLDING_MARGIN, wxSCI_MARGIN_SYMBOL);
control->SetMarginWidth(C_FOLDING_MARGIN, foldingMarginBaseWidth);
control->SetMarginMask(C_FOLDING_MARGIN, ...);
control->SetMarginSensitive(C_FOLDING_MARGIN, 1);
--- End code ---
Since all margin‑related logic consistently seems to use the symbolic constants (C_FOLDING_MARGIN, C_MARKER_MARGIN, etc.), adjusting the margin order is limited to changing the four #define values. No other code changes should be required, and no plugins or configuration files are affected.
Suggested improvement:
Reassign the folding margin to a lower ID (e.g., 1), so the margin order becomes:
Line numbers → Folding → Marker → Changebar → Text
This can simply be changed while the definition of the preprocessor constants like this:
--- Code: ---#define C_LINE_MARGIN 0
#define C_FOLDING_MARGIN 1
#define C_MARKER_MARGIN 2
#define C_CHANGEBAR_MARGIN 3
--- End code ---
I think this small, isolated change would align Code::Blocks with common Scintilla practice and improve usability without introducing new settings or breaking existing functionality.
Please take a look to this and thank you in advance.
Best regards,
Eckard Klotz.

I have increased margin size from 16 to 22 and made it dependent on scale factor, see r13915.
EDIT: Clicking in the gap between the fold box and the text editor still fires folding :o , so this change only fixes box size in HiDPI. Relating margin order, I prefer it as is.
