Greatings, The use of the Combinational Analysis option is not working properly. Do you have any idea why? Thank you for your time. ---

Sorry for the trouble caused, we temporarily rolled back simulator rewrite till this issue is addressed. ---

I’ll look into this bug and try to fix it as soon as possible. ---

Greetings, Every time I try to zoom in or out, it kind of slows down sometimes. Also, the top toolbar (which contains ‘Project’, ‘Circuit’, ‘Tools’, ‘Help’, etc.) should be partially hidden by another toolbars, but it doesn’t. Not only that, in the label in the circuit components’ properties, Ctrl+A doesn’t work as it should select the full text inside that label. Do you have any idea why it happens? Thank you for your time. ---

Will there be an option to switch to the old editor when the new editor is fully released? I work well with the legacy editor more than the rescripted. ---

No, old one will be removed. Could you clarify the parts in new simulator which makes your workflow slow ? ---

Core Dump doesn’t seem to function. I might be using it incorrectly.
