Issue/Introduction

When using XWindows to run the Spectrum Install Anywhere GUI on a Linux machine the installer dialog in some cases may hang after the installation is complete and you click the 'Done' button.

Install is Complete, click on 'Next'

 

Click on 'Done'

 

In some cases, the window remains with all buttons greyed out and has to be closed using the 'x'.

 

Cause
