Hi,
While experimenting with Darwin GTXWC build, I just
got the exact same error. (never ever got it before)

ErrorCategory= EG_ARG (1)
ErrorOS= Nincs hiba (0)
ErrorArgs= NIL
ErrorFlags=
ErrorRetries= 0
CallStack= TBROWSE:STABILIZE (794)

Brgds,

Hello Przemek
How this error can be generated:
Open any TBrowse. I did with tests/wvtext.prg <F10>.
Scroll down with down-arrow past last line by two records.
Scroll up with up-arrow past first record.
Scroll down with down-arrow and at stay at last row for a moment -
just to
be sure.
Scroll down - AND ERROR WILL BE GENERATED.
I do not know the logic so I did not dwelled deep.
