ApplyFilter works once correctly and then is ignored

[peterben]

I am writing an application (A2K)and applying a filter to a form from the selection from a combo box "SelectContact" with the following code

DoCmd.ApplyFilter , "ContactID= Forms!frmContactMaintenance!SelectContact"

This works fine on my PC and another PC but not on a third PC. The filter works once and then it is ignored.
I have noticed a MS knowledge base article Q269380 which appears like a solution.

Question is has anybody had similar experiences.
