John,
I presume you are using standalone version (WireframeSketcher Studio). There are two possible solutions to workspace problem:
- Create a shortcut to sketcher.exe launcher and use -data command line option to point to your workspace:
sketcher.exe -data d:\workspace
- Edit configuration/config.ini file and edit osgi.instance.area entry. It should look something like this (note the special syntax and slashes instead of backslashes):
osgi.instance.area=d\:/workspace
For your zip export problem, the export wizard should remember your location the next time you use it.
Let me know how it works for you.
