Hmm this is interesting.  The following script demonstrates the problem:

source combobox.tcl
namespace import combobox::combobox
combobox .foo
pack .foo
.foo list insert end string1
.foo list insert end string2
.foo list insert end string3

Under Cygwin, this works properly, however under my Linux / Xwindows 
combination, the items in the combo list are drawn *beneath* the 
containing canvas.  If I resize the default wish canvas, and create an 
entry with a very long name such as

.foo list insert end thisisaverylongstring

then I can see this text peeking around the side of the pane when I drop 
the box down (click the down triangle).

If anybody with a RedHat 8.0 box has a few seconds to spare would you 
mind testing this out?  Linux is non-standard here at my workplace, I'm 
the only one around :(

I will also try to track down the author of the combobox widget.

erk - hopefully I'll just get away with patching comobobox.tcl, or even 
better, adjusting my X server/client settings..   Do you recall hearing 
of this problem previously?

Thanks,
