Not all Windows 7 users are affected by computer crashes.
If crashes occur (in connection with freeform text), please download the latest stepup and modify the file capella.dat in your personal capella folder as follows: Add the entry RichTextPatch=opaque or RichTextPatch=opaquePdf in the area [Defaults] (you will find information about the meaning of these entries in the file stepup.html in your program directory or in the version information on the capella download page). Please observe the instructions concerning changes in the capella.dat which you find in your pdf manual on page 170.
