Problem With IsFormLoaded Do Loop Code

[Doc]

The code is meant to open a form, get input, hide the form, take the input
and apply it to the first form. Basically, if the user selects 'Other', I
want to know what the Name and Category of the 'Other' is. When the form
opens, if the user only uses the keyboard, everything works fine. However,
if the user actually clicks the combo box to select an option, it wont let
them select any of the options. Wierd.

3 chunks of code; 'CurSysRequest()' is the code that runs the main form,
CurSysRequestOther() is on a field as 'After Update', and the code that
checks the IsFormLoaded function. The IsFormVisible is exaclty the same,
only it checks if frm.Visible = true.

One other anomoly worth mentioning, if the user right clicks to try and
select an option in the pop up window, they get an error message that states
that the BeforeUpdate or Validation Rule is preventing the database from
saving the field, and then the user can select an option, but by that point
the code has stopped functioning.

Thanks in advance!!

As it turns out, I just had to move the focus to the next field before
opening the secondary form. . .
