Suddenly I find a strange problem in VFP8 Beta (still waiting for shrinkwrap edition).

The following code fails in the second line with error 12: Variable _TASKLIST is not found. In fact, the variable has a value which can be seen in the watch window. I tried recompiling, because earlier we were using VFP6 in a different machine, but no difference.

IF THIS.Visible
  THIS.Enabled = NOT EMPTY(_tasklist)
  THIS.Value = WVISIBLE('TASKLISTUI')
  DODEFAULT()
ENDIF

Any ideas of what it could be?

TIA,,
Alex
