<DIV>I am using Windows XP Professional, Service Pack 2 (on some systems, Service Pack 3 is applied).</DIV>
<DIV> </DIV>
<DIV>Michel Dagenais suggested that if the problem does not reproduce on Linux, that it might have to do with how Windows reports character events. He thought a Filter VBT may exist somewhere that would aid in debugging by printing method calls before propagating them to father/son. This filter VBT would be inserted at different places in the VBT tree to get tracing information. Are you familiar with something like this?</DIV>
<DIV> </DIV>
<DIV>As for the pixmaps, Michel suggests increasing the resolution of the original pixmap to help alleviate problems with upscaling. I may try this, but of course, FormsVBT uses a lot of pixmap resources, for example, radio, boolean, checkmark, numeric, etc all use pixmaps.</DIV>

<DIV>Regards,</DIV>
