Macros only working if I run as ADMIN

I have a Windows 7 - 64 bit machine running Office 2007. IN Excel, I am using a template in a spreadsheet that automatically populates field in a web page after you log on. THis program has always worked good until getting this new system. Now, the only way to tun this Macro in this spreadsheet is to open Excel as an admin and load the program. When I do this, thetre are no troubles. The part of the code that it stops at during the Debug is:

Private Sub WaitForIEReady()
  Do While m_IE.busy: DoEvents:  Loop
  Do While m_IE.readyState <> 4: DoEvents: Loop
  Do While m_IE.document Is Nothing: DoEvents: Loop
  Do While m_IE.document.readyState <> "complete": DoEvents: Loop
  Sleep 200
End Sub

If anyone has any suggestions or has seen this before, let me know. Running this as an ADMIN is not an option because I have over 100 people using this spreadsheet. Yes all my security setting are correct, I believe. I have enabled VB project and enablesd all macros.

Thanks,
