When editing the name of a Data Store Memory, or a Data Write Memory, it takes from 3 to 10 seconds before the block takes in account the new name of the variable. Meanwhile, I can't work on the model.

How to fix this and make it faster ? I was using a much older version of Matlab (R14), and editing a Data Store Read/Write block was almost instant. I have the problem even on an empty model.

Window 7 64 bits Matlab/Simulink R2011b - 32bits

Thank you for your help,

I am not 100% sure this will fix it, but try those bug reports:

It seems that files from bug 808560 improve the performance of the editing a little bit, but it sill remains very slow (couple of seconds before the end of the freeze). I think that the problem is pretty easy to reproduce. I reproduced it on other decent computers with Matlab 2011b.

Create a new empty Simulink model
Insert a Data Store Read Memory
Replace the name the block 'A' by another name
Try doing something else and check that's it not possible before a couple of seconds

Thank you for you help.
