Windows Tkx::tk___chooseDirectory

As a relative newcomer to Tkx on perl I have run into an issue with the 
Tkx::tk___chooseDirectory command.  I use this in an application with its 
primary interface built using Tkx, that also spawns Excel using 
Win32::OLE.

The Tkx::tk___chooseDirectory works fine before I have opened Excel.

After I have opened Excel it just freezes. The application logic allows 
Excel to be closed when using Tkx::tk___chooseDirectory, and I have tried 
all methods to close excel and free unused library information, including 
using Win32::OLE Close/Exit/Quit commands, 
Win32::OLE->FreeUnusedLibraries(); , manually closing Excel, killing all 
Excel.Exe processes.

Apologies if this is the wrong list for the question... Any help or 
direction appreciated.

Thanks
