I haven't noticed it in general.  I have always noticed it occasionally on some skins every once in awhile, I've no idea why, but what I've see is is very much skin-specific.  If the skin does it, it does it, if it doesn't, it doesn't.

You might try opening up somebody else's skin to see if it works any better.  There might some condition you guys are carrying around in your skins (I'm guessing you don't start from scratch every time).

Hmm, I was just keying/tabbing through some fields here and it does seem to be a little bit laggy.  Not as bad as the few problem skins I was talking about (a couple of those were ridiculous), but it does seem to have picked up a little lag/sputter.

Somebody may want to know - I'm on Win10.

Hi Andy,[e digicons]|-)[/e]  

We all have to admit that Skinstudio is not the best software we could have, but it has helped us do so many skins anyway.
However, the case you mentioned has happened to me only once some years ago and I corrected it with re-installation of SkinStudio or by putting a clean copy of my Windows 10 hard Disk C and re-installing SkinStudio, if I remember well.

Have in mind that sometimes I do over 50 skin corrections and applications per hour! Not in the past, but this week for example with SkinStudio version 10.1 and all work beautifully and fast.
What version of Skistudio do you use? 

I understand Andy, but how you explain that SkinStudio works fine in my computer? [e digicons]:\[/e]  

Maybe a common third party software (AntiVirus or something else) causes the issue in your computers..

Yes, that is why I said a "common third party software" to both computers...

Any way, I just wanted to help, good luck![e digicons][/e]  

How is everyone? I hope you all do fine...been a while since my last visit.
This may be not related but the latest update of my AV caused some problems with other programs...
Some of them show increased memory usage in Taskmanager, saw this post and thought you guys might face the same issue with skinstudio.
Open Taskmanager and take a look at the processes tab and see if Skinstudio is eating up an abnormal amount of RAM if so whitelist the application in your AV to resolve the issue.
This strangely worked for me for other older apps...
Might be not the case for you but worth a try, otherwise try and run it as Admin... to see if that changes anything. 

If your physical memory is full or the capacity close to be fully utilized, the running threads that need memory to do operations may write to your physical hard disk instead if the RAM isnt available, you can observe this if you open Taskmanager --> performance --> recourcemonitor -->then RAM
on the right side there should be a live graph or several, whenevery this shows a "hard error"  a thread has requested data (pages) from RAM that has already been paged out to HDD or SSD and now has to be loaded back into RAM.
if this happens often this is an idication that you need more RAM. 

Anti Virus, Andyroo.

AV

Some programs, especially older ones, may get unstable and "laggy" if you have an unusual high number of fonts installed.

Too bad... and btw.. I read flies... instead of files... I think I need new glasses or a brain!  lol!  Well, I'm sure you will make it work!![e digicons]B)[/e]  

In my OS I have installed 683 fonts, I don't think that they cause any issue...
