Bugs and restrictions

- Sometimes, cascade has got problems with mouse-drivers when returning
  from Preview (by the way: 3dv and chemview have the same problems!).

- If you are using a harddisk with power-down, cascade can indicate an 
  error when writing the ini-file or bsp.opt. Just repeat the procedure 
  or you will not be able to start cascade with your old settings! If 
  you have a destroyed ini-file or bsp.opt, you only have to write a 
  text-file with 40 lines to start cascade again!

- pdb-files converted by mol2pdb do not use many capabilities of the
  pdb format, just enough to show .mol-files with raswin/rasmol.

- The MSDOS GNU version of awk only runs on a 286 or better. There are
  also awk versions which run on older computers. The semi-empirical
  calculation programs could provide even greater problems, though.
  (They take a very long time, even on a Pentium.)
