The Windows 10 so called “Creators Update” from March 2017 caused several problems with rendering Webdynpros. One affected transaction is for example: SOAMANAGER.
Affected SAP releases are 7.31, 7.02 with SP 18. Not affected: 7.4x and 7.50.
(this list is not complete!)
Another problem was reported with transaction “nwbw”, it also didn’t render correctly anymore.
Solution for all issues was to apply Microsoft KB 4016240.
This is the cummulative rollup patch from April 2017.
