Is there a way to send u a config file? so you can try there? I think that's something that should be tested by the team, I'm lazy to have crashes until I find the cause.

You shouldn't have to hunt for or stumble across it, so that's one non-intuitive UI feature that could definitely be improved.

Is WFX5 installed on the host or the client or both?

The problem with start menu animation is quite random now, works, doesn't work, after reboot still doesn't work, then after another reboot it does works.....no clue

I'm sorry to have misled you, Neil.  Office2010 technically doesn't have 'menus'.  I should have said 'dialogs' - FileOpen, FileClose, FileSaveAs, OpenRecentFile; they all behave as windows (I assume they should) & use the Open & Close animations.  I use a 1600x900 display with right-side Taskbar and have those dialogs set as large as I can.  The Open & Close animations are choppy enough on my rig, particularly with large windows, to be a distraction so I've abandoned using them.  The Minimize & Restore animations, on the other hand, are smooth and I still use them.  The difference in quality between Open/Close animations & Minimize/Restore animations is significant on my rig for some reason.  It's Intel graphics, of course.

I've seen an issue with WindowFX's own UI, BTW - the window opens with a lot of white blocks which fill in one at a time over a period of half a second or so - which I thought at first was due to the WFX animation, but it happens with the Windows default animation, too.

I test-drove all the version 5 ones, but was mainly using Expand from Desktop or Rotate (Horz/Vert) for Open and Reverse Suction to Right for Close.

I'm using random min/restore animations currently.

I don't think the Intel graphics drivers are quite up to the job, although the GE score is 5.5 per WB About.

Thanks, Neil.

Expand from Desktop is a v4 style animation which works differently to the v5 ones so may have different performance.

I have a observation/fault when FX5 is on my open windows do not re-open on a re-start, all of the animations and effects seem to work fine on my windos 7 64bit machine but the my open windows dont re-open, any thoughts

Try turning off close animations and see if that impacts it.

If not, try disabling open animations and turn close ones back on.  Any change?

Interesting - now (open animation off, close animation on), just pressing the Caps Lock key transiently dims/transes the active window.

To be fair, I may be taxing my rig a bit - at the time I had Palemoon with 7 open tabs, 3 Citrix VPN sessions, 5 Word documents, Outlook and a medical imaging app all running simultaneously, with explorer.exe using 7-20% of CPU.  Just my normal day load.

I'll give the V4 animations a spin.

I am still on WinXP. Is WinFX 5 going to have window shadows like older version did? I always used the Mac style window shadows in older WinFX versions.
