JD,

  I never had anything before 5.2 on linux, but I also observe weird
things with these widget_list's: I see a similar behaviour change
whether I set the value in the definition statement or afterwards, only
that I never see "tiny" selectable entries. These appear normal to me.
However, I do not always get the correct ysize if I use
widget_control,set_value. It may be due to the lousy code in explore,
but when I tried it here, the two lists on the right (for a screen
snapshot of the main window, please see my web page) are cut off at the
bottom (i.e. the borderline is missing: all 7 text lines are displayed
correctly). Please submit this as a bug rport to RSI!

Martin.
