Hello !!!! excuse my english.....I'm french !!!!

I have developped an application in Visual FoxPro 3.0 on Windows 3.1 ...
My application use MSGraph and Excel....
...and I have a lot of problem with the executable version...

The application is very slow and I must have a pentium 100 with 16MB RAM for display graph

I update automaticly the graph in my application and sometimes the program fall down if I use 256color driver

What do you think of these problems ????
Do you know a solution?????

AND :
Do you think that if i use VFP5.0 it is better ???
Is it possible to translate very easely an application from VFP3.0 to VFP5.0 ?????
Is it possible to execute an VFP5.0 application on Windows 3.1 ????

Thank a lot from an poor alone french programmer !!!!

Et bonne journée à tous ...
