I have Spark 2.6.3 installed on something about 100 PCs (there are different OSs - XP, 7x32, 7x64) some of them works fine but others sometimes didnt show popup message then receiving message and in dialog window nothing appeared…Sometimes restrating Spark help with these problem, sometimes changing of skin only helpfull. There was one topic about such problm as I have but there was a patch that need to be installed but no instructions how to do these…So I ask somebody for help with that problem. What should i do to fix these problem…
