Hi, I've found a problem when using magnifier with IsoView 7.0.60.7 on a Citrix Environment. I open a CGM file, then I open the magnifier : the magnifier window remains empty. I can also reproduce the problem on Vista or XP when I change the color settings from 32bit to 16bit. The magnifier stop working. It only appears with a 32-bit color configuration which Citrix environment don't support. There was no problem with a previous IsoView version (v5). Thanks
