Unusual Window Issue on Mac/OS X

[Rotsiser Mho]

I use BetterTouchTool on my Mac to manage window snapping. It works with pretty much any application. However I noticed that applications I've created with wxWidgets, as well as other wxWidgets applications (CodeLite) don't allow the window to snap. Maybe wxWidgets windows aren't handing/exposing some event that most Cocoa apps handle/expose?

In any case it's surprising and seemingly incorrect behavior since every other Cocoa app I use allows for snapping. Has anyone else noticed this? Any ideas as to how I might pursue a fix?
