Switch/Case slow when adding cases

I have a few Switch/Cases that (IMHO) are pretty simple.

A typical one is Switch if variable is…and then the actions are just “return text”. The Switches I have might have maybe 20-25 cases max.

When I run the macro, the Switch/Case works fast and great.

But when I try to add a new case, the Editor can take ~10 seconds before it’ll actually add the next case for me to edit.

Is this normal? Is there anything I can do to speed it up?

I have not noticed particular problems with switch/case, but the KM Editor can be sluggish when it is pushed a little hard.

This is from the FAQ and is the first thing to bear in mind:

Note that while you can have more than one editor window open, it can quickly slow down Keyboard Maestro so it is generally best to only have one editor window open unless you need to refer to two macros at the same time.
