Thanks Jim. yeah, the string that works OK is 252, so if I add
anything... boom.

Of course, there's no mention of a limit in the help (that I could
find).

So any ideas on where am I going next to do this?

My guess is that you are up against a limit on the string length.
If the length of vSaveFileFilter is under 255 the dialog is displayed.
Add the line "MsgBox Len(vSaveFileFilter)" and see what you get.
