Combobox strange behaviour
 

Hello there, I have a userform (that is quite complex). On one of the pages I
have various Comboboxes with varying listrows lenghts (from 3 to 16).

When the form is loaded there are three different things that can happen:
1. Everything is normal (funnily enough, a rare ocurrence)

2. All the Comboboxes are still enabled, with the correct Listrows length
and Rowsource (checked in the Immed window), but when I click in them I
cannot access the dropdown feature, but CAN overwrite the contents manually.

3. As for 2. but each combobox shows two BLANK dropdown lines (the data
source is intact).

Given that 1. (above) only happens less than 5% of the time, it's kinda
defeating the purpose.

EH?
