On a standalone system you can get better performance for the preview window if you change the ImageFilePath to a local folder.
To change the ImageFilePath
Quit Engineering Base.
Start Registry Editor.
Look for the HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\AUCOTEC\Engineering Base\<EB version>\Server\Files key.
Modify the ImageFilePath variable to a local folder (e.g. C:\Documents and Settings\All Users\Application Data\Aucotec\Engineering Base\Tmp).
The next time you select a sheet, the preview is much faster.
This cannot be used if your computer is used as application server for other computers!
You need administrator rights to change this registry setting.
If you have Engineering Base installed on a 32-Bit Windows system, the registry entries shown on this page may be displayed differently. Please read the details in the topic about system registration in 32-Bit Windows versions.
