vbModeless form problem?

Hello -

I feel like this should be a relatively easy fix. I am trying to show a quick and dirty form (which simply says "please wait...") when a user clicks a button. The particular macro I'm working with takes about 3-4 seconds to run. I tried to figure this out using a Google search, but I'm not having any luck. The code I have now is:

frmPleaseWait.Show vbModeless

< all my other code is here>

Unload frmPleaseWait

I am using vbModeless because I want the rest of my code to execute in the background of this form being displayed so the user doesn't have to click anything to allow the code to continue. The form comes up entire white on my screen though, and it should have a grey background with the text "Please wait..."

Thoughts? Ideas? Am I doing something wrong?
