Illustrator CS5 Artboard Dialog box will not resize the Artboard
Hello Community. Thank you in advance for any guidance. Here is my setup. I've used Illustrarator CS5 for many years on my Dell Laptop with Windows 7. Works beautifully. I just bought a Dell desktop with Windows 11 Pro. I installed CS5 and it seems to work great. I am having only 1 unexpected issue; When I double click the 'tic tac toe' icon on the tool panel to resize the artboard, the dialog box appears. From there, if I change the artboard size, nothing happens. On my Windows 7 laptop, this works perfectly. On my Microsoft Surface Pro with Windows 10, it also works well. On the new computer it does not. I can close the dialogue box and manually stretch and manipulate the artboard to the size I want it, but it is not 'exact', and I feel like I'm manually doing something that should be automatic. It's also a huge time waster. I know that CS5 is not supported anymore, but I love the program and use it all day everyday for my t-shirt business. Any thoughts? Thanks a million. Dan
