Thanks for following up with your solution, Zeepee. When Hero Lab opens a saved portfolio, it does decompress the contents, but it does so to your temporary directory, not to the same folder the portfolio is in. I'm surprised that it doesn't work when the network share is read-only - that seems like a bug to me. I'll have to do some investigating with our compression library and see why it's doing that.
Would you mind emailing me at
colen@wolflair.com so I can get in touch with you later? If I can figure out a fix for this it'd be great to get a confirmation from you that it works before generally releasing it.
Thanks for posting the error message, as it'll be very helpful for tracking down exactly what's going on with the issue.
