Video resolution problens

As my recent posts might suggest, at long last our product is in the field, its gestation period taking slight more than the pregnancy term of an elephant and frustratingly finding more installation problems than we ever imagined.

Ah one tip,if you are installing on windows 98 and using Crystal Reports, in addition to everything they say you need, you also need to install a dll called DbgHelp.dll into the windows system32 directory, otherwise everytime you tryand print the report it says load report failed.

Anyway back to my video resolution problem, really weird. We based our application on a standard or required minimun resolution of 1024 x 768, ok know the reocmmendation is 800 x 600

Has anyone else found these sorts of problems and were they able to classify them and find some sort of solution to them.
