Plugin GUIs not showing

I’m having a problem with some plugins GUI’s not showing in Cubase 6. The plugins load but I cannot adjust them. Only a small part of the general editor shows. The plugs are 32 bit so maybe a problem with the bitbridge?

I’m running Win 7 OS 64-bit with C6 64 bit. It’s not a RAM issue, I have 12 Gb RAM and these plugs are very small.

One specific example is the Glitch plugin (freeware) which have worked perfectly under 32 bit C5 and C6 but not under 64 bit C6.

I had the same problem with “Glitch” and the VST Bridge. jBridge works but that is the only solution I know of.
