I started to dig a little and found that there are theme files in ~/Library/Application Support/Adobe/Flash Builder/Themes/ could my installation be corrupt?
my guess is that its not corrupt. but maybe you had an open window somewhere in FB4, hidden away, docked under another window? that happens to me all the time, but Im not on a MAC.
I just experienced this when trying to create a new skin for a spark panel. It wanted me to fill all text fields with a value before continuing on.
My guess is that you need to cancel out of it correctly (like cancel all open windows, one may be hidden behind this one?) or clear out the text fields properly.
Okay I fixed the issue.
- deleted all the folders under ~/Library/Application Support/Adobe/Flash Builder/Themes/.sdkThemeSwfCache
- restarted Flash Builder
- removed all Flex SDKs
- added the SDKs back in
- you can see that new entries are created under .sdkThemeSwfCache
