But doesn't this mean that the "tick text" feature of a slider is totally 
useless?  IBM can't require that we stick to 1 or 2 character text!

"static control" is very urgly to handle (not worth the effort in my case), 
shorter text no option (how do you shorten 100? "C"?).  Using a smaller font is 
a nice idea but IMHO one should stay in the same font family and with the today 
usage of "WarpSans.9" in dialogs there is no smaller WarpSans font.

Idea: if you take a look at the setting notebook of c:\os2\apps\klondike.exe 
(options) you will notice that the slider has three ticks but the left one 
isn't located at the left margin.  Probably the ticks are placed using 
SLM_ADDDETENT.
I could create ticks at 10, 30, 50, 70 and 90 and avoid the problem...

Bye,
