Just to clarify: taskman's "Mem usage" column == procexp's "Working set" column and this is the amount of memory that is actually being used by the process. taskman's "VM size" column == procexp's "Private bytes" column and this is the total amount of code+data that has been assigned to the process, though not all of it is necessarily in use. procexp's "virtual size" is simply a representation of the amount of virutal memory that has been allocated to the process. Virtual memory is not real memory and it only means that X number of pages have been allocated, it says absolutely nothing about the actual memory used by the process, and you should ignore it completely unless you have a specific reason to need to know about it.
