9.1i ISE - When Project Navigator is running, PDF files cannot be opened in Adobe Acrobat Reader


While Project Navigator is running, I cannot open a .pdf document for reading. Adobe Acrobat appears to hang or does not respond. The PDF files cannot be opened from Project Navigator or from other locations such as Windows Explorer.

Typically, in the Windows Task Manager, an open Acrobat process is listed. If I end the open Acrobat process, I can open and view the PDF files.


This problem is related to the OS version, the browser version, and the Adobe Reader version.

The most common occurrence of this issue is on systems using Win XP SP1, and is related to wisptis.exe. The wisptis.exe file is a Microsoft program used on tablet PCs for handwriting recognition, and is run when Adobe Reader is launched. If wisptis.exe is left running, over a period of time, it will consume large GDI object resources. This results in overall resource limitation and random display issues for other applications and for the OS.

You can work around this issue by ending the wisptis.exe process in the Task Manager along with all Adobe Reader instances and then opening the PDF again.

A better solution is to download Win XP SP2, which fixes these GUI display issues and issues related to Adobe Reader not opening links or not responding. You can also chose to patch Win2k/XP with this fix without the service pack fix. Reference 838283 at:
