At the moment it is best to stick to the wx2.8 builds.

wx3.0 builds are for people that are not afraid of crashes/asserts/bugs and they're willing to report them.

Ah, thanks oBFusCATed, I don't actually need a 64-bit build of C::B, it's more of a vanity thing.  Under Linux a wx 2.8.12 64-bit build is trivial, but under Windows where I am one is not.

@ollydbg:
I don't like the fix. We have to know the reason for this change in behaviour.
Also the check should be against 3.0 and not 2.9.5. wx2.9.x is not supported in any way, only wx3.x, thus the code should not be misleading.

I don't know the reason, I have debugged this bug for several days, until I asked in the wx-user maillist.
Eran just told me this is an workaround, this also get better performance as he said. see his wx-user maillist(in my previous posts)

I see the CallAfter's document is said this function is from 2.9.5, so I changed my first idea which is 3.0.0 to 2.9.5.  :)

I need more comments about those patches, especially Morten, because he is the maintainer of that scintilla branch. You can apply those patches locally in your computer, and test those changes too.

I tested the patch.  Built wxWidgets 3.0.2 64-bit, applied your patch to SVN 10630, compiled C::B wx30_64.  Resulting build: opened main.cpp from the C::B project, scrolled around, removed and added text, over the course of five minutes testing everything worked.  Compiler used was TDM-GCC 5.1.0 64-bit.

Ok, I did a sanity test.  I know that using MinGW-Builds GCC 5.2.0 / posix threads / seh exceptions / Revision 1 / 64-bit I had the cursor errors.  So, I recompiled wxWidgets 3.0.2 and Code::Blocks SVN 10630 with the patch with that toolchain just to make sure the issue was also fixed using that.  It is.  The patch corrects the errors.

If anyone would like to try the binaries I built in a different environment, their machine, you can find them: Here.
