When using Notepad++ (tested with 3.2 and 3.3) together with BlackBox (bbLite 1.16), trying to use the find command (whether invoked by Ctrl+F or the menu item) causes Notepad++ to crash, with a messagebox saying "System Err: The system cannot find the file specified."
If I add Notepad++.exe to the bbLeanSKin exclusions.rc , it works without any hiccups though. The interesting thing is that I can continue using Notepad++ if I don't click the OK button in the messagebox. Also, if Notepad++ is in the exclusions list, and I start a copy of Notepad++, remove it from the exclusions list, and restart bbLean, notepad++ becomes skinned... but doesn't crash on CTRL+F. If I then close and re-run Notepad++, I get the error again.
I'm posting this to both NP++ and BB forums, but I think it's most likely a bbLeanSkin bug...
