Securus:  
This is known not to work with Wordshark 3s or Numbershark 3. The firm tell us that their product scans the screen frequently for inappropriate language. This scanning, plus the graphics power needed to run our software, normally results in freezing. We understand that it is possible to disable the scanning by Securus whilst our program is running.

Anti-Virus Software (including Norton Symantec McAfee etc)
We advise that you disconnect from the internet, and disable anti-virus software during installation of Wordshark and Numbershark. Re-start to re-enable afterwards.
Slow running of Wordshark and Numbershark has been reported on some low-spec computers which are running anti-virus software. This is not a conflict, but a symptom of insufficient memory or processing power to run both programs at the same time. If you are affected, we suggest you disconnect from the internet and disable virus scanning whilst running our programs.

Daemon Tools, Alcohol, Nero, Clone CD and similar  Cd copying programs:
These utilities need to be uninstalled or disabled whilst Wordshark or Numbershark are being installed or run.

Virtual CD Drives
These must be disabled before running the single user versions. Network versions are not affected.

Dolphin Supernova:

We are aware that running Supernova  version 6.51 in combination with either Wordshark or Numbershark, you may experience intermittent freezing, text or graphics "left behind" or problems with pulldown menus.
These problems cease when Supernova is closed. We have found that running our “Fixgraphics”  utility overcomes this conflict, allowing our programs and Supernova to work together.  Note that other versions of Supernova may be similarly affected.
Please visit www.dolphincomputeraccess.com and try the most recent version of this software to determine whether Dolphin have been able to fix the problem.  

Dophin Computer Access Ltd has confirmed that the screen corruption may alternatively be resolved as follows:
1. Open the Supernova control panel with LEFT
CONTROL+SPACEBAR
2. Open the "Configuration" menu with ALT+C
3. CURSOR DOWN to "Video Engine" and ENTER
4. TAB to the "Direct Draw / GDI+ compatibility mode"
checkbox and press SPACEBAR to select this.
5. TAB to "OK" and ENTER.
