I have issued an update to Ini++ v1.5. It fixes a couple of memory leaks do with the undo stack. The memory leak applied even if the undo stack was disabled. For this reason it is important that every user update to the latest version.
In addition, a minor bug is fixed where the undo and redo stack size could be set to 128 layers. This would actually register as infinite. Now the properties panel will not allow any values greater than 127. If you previously choose 128 it will stay selected, so you ought to be aware of this.
There are still known bugs. I have been able to reproduce a crash with the encryption. Hopefully I’ll be able to fix this in future, but I do not have the tools available to do so quickly. I apologise for the instability. Thank you to HitmanN and XStar for sending me examples of these problems.
