avoid error 3035 not enough system ressources
opening too many forms with a 32bit MSAccess Version can lead to error 3035. In this case some Actions are ignored. The cause is not enough virtual Memory.
This error is hard to handle because it is difficult to reproduce as closing forms does not free all used Memory.
- use less virtual Memory and free all used Memory when forms are closed
- make it possible to better hanlde or avoid such problems
