I tried the newest nightly build version, the bug that I found before is still not resolved.
Please see the shortcut unusual.png.
Pre-condition : at least two projects.
os : win7 64bit
Repetition steps:
1 In the default workspace, open two projects, each project to open a file.
2 Close the default workspace, and all projects also closed.
3 reopen the two projects.
Note:
If only one project have file opened before close workspace, all is right.
