mouse drag&drop broken

When I select some text, and at the same time double-click and move the mouse (needs some practice..), the mouse freezes with the drag&drop selection cursor. I also can't click outside the window or anything. Keyboard keeps working, so I can continue editing with the keyboard, and exit CB with Alt-F4 - at which point the mouse starts working again.

This is rather annyoing, since of course I never do it on purpose, but after some time of editing, it always happens.

One way to work around this would be if you can provide an option to disable the selection drag&drop (or if there is, I didn't find it..) - I never voluntarily want to use it anyway. Also, most other editors don't have such a (rather weird IMO) feature - but anyway, this report is about the bug with it.

Assuming this has more to do with the underlying editing component or window manager than CB, here's the version information from Debian's reportbug:

Umm what version of C::B RC2?

If so get this nightly build.

Also, you need wx2.6.2. You have wx2.6.1. I think the problem is that you have an old wx version.

This is a known scintilla/wxscintilla (editor) bug under gtk.

Ok, I upgraded now to CB from SVN, and WX 2.6.3 (SVN), and it seems like the freeze bug is indeed "gone" there, instead of freezing, CB simlpy aborts now. Since I'm already here, this is the backtrace I got:

I can try compiling a version with full debug info, and try without plugins..

To reproduce, I simply took a file (first a big C++ file, then a file with just a single "a" in it) as start, and then clicked and drag&dropped like mad. Both times I suceeded after about 5-10 seconds.

Should be fixed with patch 1037 (applied earlier today).
