I have a user that when they zoom IN to a graphic the screen background will go black. He had this problem previously when we were running IsoDraw 7.1. We have now upgraded to 7.3 F000 and the problem has returned. We have tried the fix listed below but it does not seem to do the trick this time;
CGM graphics viewed in Internet Explorer using IsoView display as white graphics against a black background. This happens in NSIV and when CGMs are viewed from the CSDB.
Navigate to the following location: C:\Users\<user id>\AppData\Roaming\PTC\IsoDraw\Preferences
If the AppData folder is not visible, the folder options to view hidden folders/files must be set. See process at bottom entitled “View Hidden Folders”
Locate the file IsoView 7.2 Preferences.prf or IsoView 7.1 Preferences.prf. If you have both files the following process will need to be applied to both files.
Right click on the IsoView preference file (IsoView 7.2 Preferences.prf/IsoView 7.1 Preferences.prf). Select “Open With”, “WordPad”. If WordPad is not available as an option, select “Choose default program…” The “Open With” window opens, select the “Browse” button. Navigate to C:\Program Files\Windows NT\Accessories\wordpad.exe. WordPad is now set in the Open With window. Select “OK”.
The preference file opens in WordPad. Scroll down to the text line “Use OpenGL for 2D: 1”. Edit this line by changing the one to a zero. The line then reads “Use OpenGL for 2D: 0”.
Save and close.
Restart the computer.
We do have the M020 update available will this cure this problem? Any help on this problem would be greatly appreciated.
which graphic card did you use?
We had the same problem with an internal Intel graphic card thru an automatic update from Microsoft. The newest Intel driver has a bug. So we installed the former driver and the problem was gone.
