I am having the same problem, multicharts "running out of memory" how can i solve this problem.
In my PC there wasn't the key [HKEY_CURRENT_USER\Software\TS Support\Power Language\StudyRunner] i ad "NumberOfThreadsOnOptimization"=dword:00000002 but nothing changed when i start multicharts all cores are used and when the memory is over 1GB the out of memory message is popuped.I have 6GB of ram and when i get the message the total usage of ram is under 50% of the 6GB.On http://www.bigmiketrading.com/multicharts/15987-my-problems-multicharts-3.html I find that on of Multicharts's assistent posted a file named NumberOfThreadsOnOptimization.reg do you have that file?Can you attach that?
