wine users - Mar 2007 - Dreamweaver 8: "Design view" only partly visible, "Source view" completely

Hi,

Dreamweaver 8 (installed, not copied) under Wine 0.9.32 and Kubuntu 6.10
shows a strange new effect:
The source view is completely visible (e.g. 1000 lines), of the design
view you could see only a small part (first 80 lines).
The scrollbar in the design view appears as if the document is only 80
lines long.

The effect is new.
Until yesterday it did not appear.
I didn't change anything at wine or DW.

Do you have any idea how to solve the problem.

DW is the only windows application which really has to work after my
migration.
I hope anyone has an idea to get it work.

Andreas
