Hi guys!
I developed a small applet which workes fine. Yesterday, i wanted to view it in a res. of 800×600, since most users in our enterprise seem to use that res.
Everytime i use the applet in 800×600 at a certain dialog, it throws back following error:

TfcControlDialog.Execute Exception
Details: [System Error. Code: 1400. Invalid WindowHandle]

<- (the invalid windowhandle is a translation by myself so it maybe a bit altered in original)

Everything works fine again, if i switch to res. 1024×768..
The dialog, where the applet crashes, has nothing special in it.. its size is 400 x 550 wich shouldnt be a problem too..

I dunno what to do! Would appreciate help on this one, since i cant figure out..
Thx in advance!
Tom
