If I make a change in the form, it freezes everytime. The only way is to close the program and start again.

Hello,

I have cloned your forms and made changes on them but I was not able to replicate the issue. I suspect that this is specific to a part of your form. With this, may I request that you share with us the information on which form this problem is happening and to which part of the form you are trying to edit?

As a measure I also have just cleared your form's cache, just in case it was a cache on our end's problem.

Please let us know also if the problem persists.

Thanks.
