2. System map view feature conflicts with other software that also utilizes the system map view resource
|
|
This issue may cause other software not to function correctly. Because of this, the feature has been disabled by default in the new release.
|

|
To manually enable the system map view feature:
|
|
1.
|
Open the Registry Editor (regedit.exe).
|

|
|
4.
|
Restart the scan engine services for the new setting to take effect.
|

|
3. Citrix/Terminal server performance issue
|
|
Server performance will drop dramatically because the close table entry is too big.
|
|
|
4. The ClearCase issue conflicts with the Citrix problem

|
|
|
