Option/combo menus crashing Rev

[Gordon Webster]

Dear Revolutionaries

As a test I reduced the number of items in each menu
so that all items could be displayed in the dropdown
view, without scrolling. Now the menus are stable and
no amount of clicking in them or selecting items
causes rev to crash.

The problem seems to be the scrollbars that are needed
when there are more items than the dropdrown can
display. Is there some scrollbar timimg or delay
parameter that can be reset to make the behavior of
these menus more stable or are combo/option menus with
scrollbars inherently buggy?

I guess it could also be some special character that
is no longer loaded into the menu list. Is there a
problem with certain characters in menus (like @ for
example)?

Best

Gordon
