Intermittent Slowness in Access

I know there are a lot of articles with advice about faster performance in Access, but this is an intermittent problem.  Even when using very simple queries, this problem still occurs.

We have several Access forms which, at times, take as long as 2 minutes or more to load.  Normally, they take about 5 seconds to load on average.

The database file has links to tables that are located on a network drive.  The database itself is on the local hard drive.

The only thing I can think of is that some forms have lookup tables and multiselect dropdown lists.  I am considering the possibility that the solution is here (http://support.microsoft.com/kb/918575) but I have not tried this yet, and thought it may have been fixed in the latest service pack, so was wondering if there are any other possibilities.

Other than some sort of intermittent slowness with the network, sounds like the A2007 issue in the KB.

Actually that KB articles doesn't seem to have helped.

Basically we've narrowed down the problem a little.

Se have simple forms that opens well.  On that form, there is a link that opens another complicated form with a tab control and a lot of objects inside.  At that point, even after the 'big' form is closed, everything starts running at least 10 times slower.  I can't tell if resources are being tied up or what it is.

Open Task Manager and check the Processes, sort Descending - see where ACCESS.EXE is.

Are there any calculated controls on that from - that could be looping? Any Conditional Formatting?
HUGE Row Sources for List and/or Combo boxes ?

Stuff like that ...

The usual trick with tabs/subforms is to set the Subforms's record source 'on the fly' - as needed, ie ... the first time the user clicks on that tab. This makes the perceived loading time much faster.

One of our problems had to do with some unknown (corruption?) issue that was solved by rebuilding the form from scratch and creating is on a saved query.  But it is still happening on other forms to a lesser extent.  Setting the recordsource on the fly is an excellent suggestion.  I haven't tried it yet but I'm sure it will help a lot.  Thanks.
