E-Maculation

First off, I apologize if this question has been asked elsewhere, but I searched and didn't find it.

I had previously run SheepShaver without issue on a 2011 iMac, and now have tried to run it on my new 2017 5k iMac running 10.12.6. My storage volume boots properly, and SheepShaver mostly works without issue.

EXCEPT: some mouse clicks are ignored, seemingly at random. For example, I will click on an icon within SheepShaver, say the hard drive, and the click will be ignored. I keep clicking, and, eventually, the click is registered. This behavior is making it hard to use SheepShaver, since double-clicks are all but impossible to execute.

I experienced the issue in the 2014 build of SheepShaver, so I tried updating to the latest build, but the issue remains. I've also tried different refresh rates without success.

Here are my machine's specs:
iMac Retina 5k, 27-inch 2017
4.2 Ghz Intel Core i7
24 GB 2400 Mhz DDR4 RAM
Radeon Pro 580 8192 MB

Thanks in advance for any help you can provide.

Which OS are you emulating in SheepShaver? What screen resolutions are you setting for the guest OS?

Hi there -

I'm emulating 9.0, and I've tried various resolutions; currently, I'm using 1920 x 1200. Note: on my previous host machine, I didn't experience this issue at all, and I'm using the same Mac OS 9 volume and data.

Hmm... I wonder if it has to do with the 5k screen? I'm also not having these issues on my 2015 13" or 15" MBPs.

I do have similar issues on BII with specific screen resolutions though; changing the resolution fixes the problem for me.
