I have a data entry form in word with a multipage.

If the user moves away from the tab, I run a check to see if the data is
correct.  If it isn't I display a message telliing them what is wrong and
move back to the last tab.

On my development machine this works perfectly.  The following line of code
 wizActionPlan.Value = m_lngCurrentTab
makes the wizActionPlan_Change event run and everything rolls back.

The the Citrix application machine runs the above line of code runs, and
actually changes the tab at the top, but the user is still seeing the
controls from the tab they moved to, not the ones that they moved back to.  
You can even click into the controls and do things.

Thanks
