Poor Performance and Slow Mouse When Running Visual Fox Pro via Secure Global Desktop (Doc ID 1294865.1)

Last updated on APRIL 06, 2017

Applies to:

Oracle Secure Global Desktop - Version 4.5 to 5.1 [Release 4.0 to 5.0]
Information in this document applies to any platform.

Symptoms

Performance issues may be seen with the Visual Fox Pro application (Allegro) when accessed via Secure Global Desktop (SGD).  These reports trend towards two types of errors reproduced frequently:

  1. When trying to expand a menu of the Tool Bar by positioning the mouse on the Menu Word, the automated expand takes longer than expected. For example, when moving the mouse from right to left and position the mouse on Processes menu, it takes about 2 seconds to expand the menu.
  2. Attempts to expand a sub-menu by clicking on a menu may sometimes fail.

 

NOTE: In the example, the application runs on Windows 2003 Enterprise Edition Service Pack 2, and Windows Terminal server had been updated as described in the Microsoft Technical Note:

     http://support.microsoft.com/kb/258537/EN-US

This improved the perceived performance when run from the Terminal Server directly, but did not improve performance of applications hosted via Secure Global Desktop.
