Gif and Jpg on form troubles

When I have a form with a GIF of JPG (small or big) placed in it, I get really weird stuff when I try to go to Designer-mode.
If I click in Designer-mode on the form, bits and pices start to appear.
The only thing i can do is go back to browse-mode.
As soon as I remove the GIF or JPG…there’s nothing wrong.
Also noticed if I set the GIF or JPG transparent off, the problems also disappear

I have a cleanly installed laptop (yesterday), with only Office 2000, Sybase stuff and Servoy, Java SDK, Mediaplayer, Photoshop and MSN Messenger ( at first I thought my Windows system was messed up)…

Servoy Developer
Version R2 2.1beta4-build 302
Java version 1.4.2_04-b05 (Windows 2000)

these things should be fixed with 2.1b5
