Balsamiq Lag (Actions Slowed)


Was on balsamiq 3.5 and now on Beta release. I recently noticed that after a short while, all my actions within Balsamiq (moving templates, double clicking, typing, etc.) have slowed down and is incredibly laggy. The file itself is around 2 mbs so there’s not much within the mockup. Is there a reason for this lag?


Hi @Ydan13,

Sorry for the snag! Both version 3.5.5 and beta 3.999.398 seem to behave fine on my end.

Are you experiencing this issue only with this file?

If so, could you share the BMPR file (via so that we can try to reproduce the issue here? We will keep your data strictly confidential and only long enough to try to debug your issue.

If the issue can be reproduced in any file (even a new project), did you notice some specific steps that lead to the issue?

Sorry again for the trouble, we’ll do our best to help!


Hi Virgin,

I will see if there is a issue with strictly this file! I will let you know
later today.
