I run Lightroom 4 on a Windows 8 pc. When I try to export images, I use the file settings to limit the size of the export images to a specified size (2000 K). When I ran LR4 on a Windows7 pc, I had no problems, but using the same settings on a Windows 8 PC, I get an error message after the export is completed indicating "some export operations were not performed" along with a list of files. When I look at the export destination, all files are present, but the size of the files do not meet the 2000K limit I asked for.
As I mentioned, the settings are the same as I used without issue with a Windows 7 PC. I have run both LR4 and LR4.3 with the same results.
Is this a known error? Is it being addressed? When can I expect a fix? This significantly impacts my workflow.
