Is there any way (certain syntax needed) to get all files of specified types to display in files portion of dialog when specifying multiple file types (egs. "*.png,*.bmp,*.jpg) for the pattern input in Open/Create/Replace fx? When one specifies just one type (eg. "*.png") in the pattern input, all files of that type display in the files section of the dialog as expected.
I am answering my own question which is clearly addresed in the help for the Open/Create/Replace fx. The items must be separated by semicolons (not commas as I was doing).
