"A call to an OS function failed"
"Cannot make a visible window modal"
Thereafter, if I try to delete the movie information for which the script was run, that 'delete' function hangs. The catalog doesn't even let me enter the original title of the movie--the field remains blank though the catalog registers the keyboard strokes--manually (all the other fields except 'original title' accept manually typed data). I have to use the task manager to close the catalog.
I have uninstalled and reinstalled the catalog but the issue persists.
Now I can use the catalog only if I create a new entry manually all the way through. If I use a script, any script, one of the two failures posted above appears and the entry becomes a fixed dead entry in the catalog in the sense that I cannot even delete that entry (and it imports information only in the URL and 'Comments' field. I use the IMDB script and all the other fields remain blank.
Here is what I get when I try to delete the 'dead' entry:

At this point, 'end task' in task manager is the only option that works.
Any help would be much appreciated.
