Re: [wxVTK] Middle Mouse Button And Scroll Wheel Events

[Kerry L. <lo...@gm...>]

I should have waited to try this before sending my previous message because
it was easy and took < 30 seconds.  Shang, your suggestion fixed the problem
- I added SetFocus(); to the top of the OnButtonUp() function in wxVTK and
the problem went away.  Thanks for the help!
