K2 has released a statement announcing the immediate end to security updates or technical support for Microsoft Internet Explorer versions earlier than IE 11.

On Tuesday, January 12th, Microsoft ends support for Internet Explorer 8, 9, and 10. The end of support means that these older versions of Internet Explorer will no longer receive security updates or technical support.

As such, K2 will also no longer release fixes or patches for these older versions of Internet Explorer. You may continue using the older browser versions with K2 products, but if any issues arise K2 will not release fixes or patches for unsupported browser versions. You will be required to upgrade to a supported version or use a different supported browser.

Endgaget reports that these older versions still have an estimated 20% market share.

I have a new VM with blackpearl 4.6.9 and Internet Explorer (IE) 11 loaded on it. I’ve never been able to get the built-in reports inside K2 Workspace to display correctly — if they’d display at all, it’d just be for a quick moment — like a flicker — and then, nothing.

I was assuming the issue was something with the display resolution inside the VM. But this morning I got a tip from a coworker that proved otherwise. He told me that IE 11 has a known “flickering” issue. His recommendation — which worked like a charm — was to add the domain to the browser’s Compatibility View Settings list.

Open IE 11 and go to your K2 Workspace. Click on Process Overview to observe the default state — if your display was like mine, you’ll pretty much see a blank white screen. Now for the fix: go to Tools (in the upper right corner of the browser; the gear icon) and select Compatibility View Settings.

In the Compatibility View Settings dialog, add your workspace to the list of sites.

IE 11 should refresh, and your Process Overview report should now be visible!


At this early date there seems to be conflicting information out regarding the new blackpearl’s support for Microsoft Internet Explorer (IE) 11.

As of yesterday, the Compatibility Matrix shows IE 11 as unsupported. Yet the New Features List for blackpearl 4.6.9 says it IS supported, and offers this KB article with instructions for a workaround to allow the K2 Workspace and other portals to render correctly in the browser.
