Hi Erik, Thanks you for your message, I am sorry that you are having issues using R2012b with your large Simulink models.
We have seen this behavior with other customer models in R2012b, and we have been able to help them address the issue. Our support team has the resources to help with this investigation, and I recommend you contact them by email or phone so we can help you our as well.
Thanks, Seth Popinchalk

When clicking a block it sometimes takes ~1 second for the block to open. Having quite large models this leads to lots of extra time clicking through the different blocks. This was never a problem in 2007b. > > Have you experienced something similar? Is there a way to get around this problem? > > Best regards, > Erik
