I've been running Mathcad 15 M010 for the past couple years. I've been a using Mathcad since 1995. It runs fine with my worksheets with the occasional crash. I saw there was an update in December to M030 so I installed it yesterday. It runs extremely slow just opening and calculating a worksheet. I uninstalled and went back to M010 and it works fine. M010 will run through the caclulations in about 10-15 seconds whereas M020 or M030 take over 2-3 minutes
This is not one particular file. I tried multiple different projects and it nets the same results. I use scripting (drop down pick lists) and reference files in all my worksheets.
About 6 months ago, I did the same experiment with M020 and M010. M020 was slow as well. This was on my other PC with Windows 7 x64. The recent test was on Windows 8.1 x64.
For now I'm back to M010 in Windows 8.1....no issues with 8.1 except for when I print to adobe PDF, the filename has some Asian characters in the filename. I attached a screenshot of this issue. I can live with this. This didn't occur in W7
Any idea what may be causing the slow down between updates?
