Balsamig Hangs on pnf export


Balsamiq hangs after multiple exports to png files. I must force close BM and restart. It will then start exporting again. The png files are about 1mb each.

Ugh, I’m sorry about that @Catherine_Murphy.

So they will export fine at first, but will start hanging after you do several exports - is that right?

Exporting is one of the most expensive operations that Balsamiq Mockups 3 does, and there is a memory leak that we haven’t been able to track down yet (we fear it’s related to the underlying framework). After a while, the app just gets grumpy. I’m sorry about that.

The next version of the app shouldn’t have this issue at all. We have re-wrote it from the ground up to avoid hard-to-fix issues like this.

In the meantime, if you restart the app after 10 or so exports, that should mitigate the crashing. I know that’s a terrible workaround, but things will be better soon.

Please let me know if you have any questions about this, or anything else.


Thank you for your response. I will restart after 10 exports.
