i haven't been able to see that yet... i had a time trying to do the screen grab 
because as soon as i'd hit the print screen key, the popup would go away... i 
had to try 5 or 6 times before i got the image i posted showing it...

nice! i have generally installed that in the past but didn't understand this was 
what it was for... i haven't gotten around to trying to use it, either... it has 
been on my TODO list for a long while and no projects i've been working on have 
needed it... probably because they're mostly all command line text mode 
programs, i guess...

i knew that someone (you i think) had been working on this by the posts in the 
various lists... i'm glad to see that your work is coming along nicely...

i get the shadow but not the border... it is somewhat unsettling to have a box 
popup that might not be noticed as a popup box at first... initially i had 
thought that some sort of formatting thing had happened and i moved to try to 
clear it up when the box disappeared with the text i was going to try to clear 
out... it took me a few minutes to realize that it was a popup and that it was 
due to my mouse having moved over something that had a hint box associated with 

i actually don't mind the white (or very light yellow) background of the popup 
box but the missing border is something else... why it is missing i have no 
idea... that's why i posted asking where i need to go to adjust the colors for 
those items ;)
