My problem is not with wxWidgets itself but with links your program is doing to the wxWidgets. if you can please tell me the wxWidget version you used, I'll use this one instead the version I'm using and I think it will solve the problem.
I currently use version 2.9.4, but chances are high that it will work with 2.8.12.
but was version 2.9.4 the one you used when you built Version 4.0.0 of the DRS4 oscilloscope program, or was it an erilar version, and if so, do you remeber what version it was?
I used 2.8.12 for Version 4.0.0.
