Unified patch

Thanks for your contribution, I will merge that patch soon. Could you describe under which circumstances this problem occurs from a user or developer perspective?

Sorry Marco, It happens only on the wxMitk version when I press a key used by VTK.

Status?

I think you can close this issue. I apologize for the confusion.
Best,
Xavi

The code has not yet been merged. As I assume there is a reason for this and Marco is currently on a conference I will hold of closing the bug until he has the chance to comment on it.

Thanks for your fast answer.

Marco says to merge it. Taking over.

Need core modification, trivial changes.
