Is it problem with Lazarus/fpc or maybe its something with GTK?

Any proposition? btw my gtk version is 2.10.6 should I upgrade it to
newest version?

Create a bug report with an example project.

binary created for gtk2 don't work under gnome, program exit (crash)
when trackbar is moved to minimal value, zero in my case (same
binaries work under kde). gtk works fine.

I didn't check with 9.22 for linux.

9.22 for win32 have new huge bug with trackbar. As you move slider or
try to get .position it become 0. I moved back on 9.20

Win XP SP2, Lazarus 0.9.22, FPC 2.0.4.

I experience that the TTrackBar.Position is always zero, no matter how
the slide is moved or what kind of interval is set by min and max
variables or what default position is set.

This bug has been fixed in 0.9.23.
