I'm running MUSHClient 5.02 on Windows 10.
In a world with 624 triggers in 33 groups, the tree view is unusably slow, taking several seconds for my screen reader to read the new item when arrowing around in it.
Is this the stock MUSHclient installer from mushclient.com?
The reason I ask is because I have received some slowness reports related to screen reading from some people with the Aardwolf setup. The cause in my case seems to be some kind of incompatibility with the MSVCR100.DLL that I distribute, but I haven't rolled a permanent fix out yet because of personal delays due to living in transit. People who report the problem so far on my end say that they already have another copy of that DLL installed in their system, so removing the one I stick in the MUSHclient folder has so far been a feasible temporary fix for those reports. Unfortunately, I can't just remove it from the package without rebuilding the included DLLs to not link against it, which is difficult for me to do at the moment.
Yes, this is with stock 5.02. I just tried by taking my world file and putting it in
the stock 5.02 (without plugins).
I'm also using Windows 10 X64, if that makes a difference.
