SalFrame positioning always occurs relative to the parent,
that's true. 
If there is no parent, the coordinates are desktop relative.
Also since 
you use OS/2 there may be problems regarding top/down
direction. VCL's 
implementation assumes that ascending y-direction goes
downward (like 
all windowing systems aside from OS/2 do).

Sadly no.

Please feel free to ask. VCL problems are probably best
discussed at
