Ok, It's become evident that in the newest update to Lrc version 11.0, subject/sky select will not work if the computer has an older Intel Graphics driver (and by older I mean over 2 years old).
Some users are able to correct the problem by merely updating the driver. Other users like myself cannot upgrade the generic Intel driver because the computer manufacturer (Acer, in my case) has made customizations to the driver and it must be upgraded from them and no upgrades are available.
My question to Adobe is: Are there any plans to modify the software to make it more compatible with older drivers? An if so how soon should we expect the update?
One very simple thing Adobe could do is have Select Subject and Select Sky obey the setting of Preferences > Performance > Use Graphics Processor (or introduce a separate setting for Select). In my testing, Select runs correctly when there is no enabled GPU, albeit more slowly (1-2 seconds with GPU, 5-10 seconds without). See this feature request:
