Big performance problem since Windows 10 (1803)
Since Update 1803 of Windows 10 there is a big performance hit in Visio. The access to the Visio API is much slower than with older Windows versions. It can be easily reproduced using a small macro which reads/writes user cells of a shape several times (e.g. 1000 times in a loop).
We tried several versions of Visio It seems to be a problem of the Windows update.
We use the Visio API extensively and have big problems now. Can you help me?
