When I start Affinity Publisher on my T430 laptop with Windows 10 I get a flash at the top of the screen which lasts about a second saying Affinity Publisher is not responding. This also happens on Affinity Designer but Affinity Photo has not done this. This is only temporary and the program carries on working properly afterwards. I just think it is a bit strange and wonder if anyone else has this symptom. I do see that fontdriver host is activated and takes a while to finish its processing in the background and wonder if this is something to do with it.
I have 892 installed fonts. 16 GB ram. Core i5 Duo third gen processor. I'm running from ssd. Process Lasso is running in the background to help prevent system lockups.
Publisher Version 1.7.3.481
Interestingly after loading and closing Publisher a few times this behaviour reduces. So I'm wondering if it is something to do with Windows 10 memory management issues.
