I have been running SolidWorks 2016 January this year, and I recently have encountered an issue trying to edit the font type/size/etc. of text in a sketch. When the text properties come up in the feature manager design tree after double clicking on the text, there is a partial black box around the text input box, and there are no options underneath the box to alter the text in any way.
I was running SP2, and I just tried updating to SP3, but it did not fix the issue. I have uploaded a picture of the issue I am having.
Any help is much appreciated!
