LV-Fields are flickering ....

[ReFran 14]

Hi,

I want to change a bigger script (at least form me) to $GUI_DROPACCEPTED based on examples for Global $WM_DROPFILES = 0x233.

Perhaps someone can have a look at the following extracted scriptlines with the LV-fields flicker.

If I do the same on one Main_GUI with a LV on a tab it works fine (-without flickering -), but if it is possible I want to keep the structure of the script and not rewrite all.

Is there any know limitation that $GUI_DROPACCEPTED / $WM_DROPFILES works only ont he Main_GUI.

Best regards, Reinhard

Edit: Forgot to remark that without Case $GUI_EVENT_DROPPED the Tabs are working fine.

Started new from a early version and got it to work (also if I don't know where the difference/problem is).
