I have actually also seen the copy and paste problem when upgrading to Rev 3803 from a significantly older version (3140, think). I fixed the problem by deleting the "Documents and Settings\...\Application Data\codeblocks"-folder to delete all old settings. It is a bit tedious to manually restore all the options and settings, but it did fix the copy-paste problem.
I haven't tried upgrading to this version yet, so I can't say if the problem will reappear.
another thing you can do to fix this, without deleting
all of your settings... :shock:
is to go to Settings > Editor
and then in the Editor options, go to Keyboard Shortcuts.
in the tree, find Edit > Special Commands > Line, and remove the shortcuts for Cut, Copy and Paste.
then while perusing the tree, go to Edit and add the normal shortcuts to Cut, Copy and Paste.
there ya go. no settings files deleted, no having to reconfigure compiler settings, and no need to redo syntax highlighting colors
hope that helps a bit
