Designer
*PAM-31465
Launching Software AG Designer can significantly slow down and freeze on Windows 10 if Windows Defender is enabled. The workaround for this issue is to add the SoftwareAG\Designer directory to the exclusion list for Windows Defender. Steps for adding to the exclusion list can be found in https://bugs.eclipse.org/bugs/show_bug.cgi?id=548443#c28.
