Open App From Another Workbook - Screen Refresh

I've developed a complex dictator application, which pretty much takes over the entire Application object. During beta testing, I've had some user complaints that, once my program is started, they can't access their existing workbooks.

In order to remedy this situation, I'm trying to construct a front-loader workbook, which will automatically determine whether or not to start a new instance (application) of Excel. If the user already has a workbook open (i.e. "MiscBook.xls"), the front-loader will start a new application; otherwise, it will just use the existing application.

My "Auto_Open" code for the front-loader workbook is shown below:


Sub Auto_Open()

Dim xlApp As Excel.Application
Dim wbkTemp As Workbook, wbkApp As Workbook
Dim lCount As Long
Dim vTemp As Variant

The code works fine, but I have a minor gripe: every time a new application is created ("Else" in the "If-Else" above), the screen doesn't appear to refresh. In other words, I get a new window (instance of Excel), but none of my custom-defined buttons and menus show up. If I hover my mouse over their intended locations, they "appear" one at a time.

I'm just wondering - is there something I can do to prevent this behavior, or "refresh" the new application window upon startup? I'm essentially looking for something like "Userform.Repaint", only for a brand-new Excel Application object.
