I discovered that in my recent modifications to the filename selection code in ImageDisk, I introduced a bug which can cause it to close one too many windows when you are entering a filename and supplying the extension (if you don't supply an extension, ImageDisk will supply the default ".IMD" and all is well) - The symptom is that you appear to be back at the DOS screen, however the program is still active so you keyboard does not appear to be working. I have corrected this and updated IMD108.ZIP on my site (which now shows 1.08a when run).
