My Access app slowed down

[MaxZak]

I've had a problem with an application written in Access 2k that has 1 hundred of linked table, about 1 hundred of Forms, 20 Reports and 30 Queries.

I've added some forms to that app, and I've noticed that it slowed down very mutch. As I've modified it with Access XP, I'm asking if the new file isn't optimized for Access 2K and, consequentely, slowly.
Another limit could be the file size: is there a size of an mdb file over witch the file isn't handled in a "fast way"?
My mdb is about 12MB (only forms, reports, ecc... tables are linked)

Tanks, and sorry for my poor english!!!

Ok, I've found it:
I've just created a new mdb app with Access 2000, imported all Forms, Reports, etc. and it works faster (2-3 times)
It's courious that the new Access 2000 app (compacted) isn't the same size of the Access XP app (compacted)... the 2 files aren't equal!
