A wierd thing is happening to my visio diags, the fill of any shape on any drawing, old or new, has or is being altered, took me a bit of time to work out why but it looks like it is related to the addition of rounded corners.
I can use the out of the box standard shapes to create a simple rectangle, it will have a solid fill, the moment I add rounded corners it changes.
Infact the fill of anything I open that has rounded corners is rendered the same way, also drag a shape from a stencil, the moment it lands on a drawing the fill changes.
Was fine two weeks ago, I've not used Visio since....I'm racking my brains to see what has changed, only significant thing is a Windows update that I had been postponing for as long as I could.
Please see attachment for example, drawing was based on basic diagram shapes, it shows a few straight corner shapes and what happens when I change the corners to rounded....
