This sounds more like an fvwm/X issue than an IDL one. Do you have
something like:
Idl*background: #7300a100ff00
Idl*XmText.translations: #override \n\
<Key>osfDelete:
delete-previous-character()\n
Idl*visual: PseudoColor
Idl*colors: -5
in your Xdefaults (or .Xdefaults) file? What output do you get when
you do HELP, /DEVICE? Also, you should include your OS and system info.
You can always use keyboard focus events to have your widgets restore
the appropriate color-table when the mouse enters. See the online
help for WIDGET_BASE() under keyword KBRD_FOCUS_EVENTS. Then put
something like this in your event handler procedure:
name = strmid(tag_names(event, /structure_name), 7, 1000)
case (name) of
"KBRD_FOCUS": begin
; Entering program area so load colors
if ( event.enter eq 1) then $
tvlct, state.red, state.green, state.blue
end
"WIDGET_BUTTON": begin
...
endcase
Hope this helps.
