PAT for Windows will now handle larger numbers of atoms

In a recent student exercise we wished to simulate the pattern for a fragment of a metal complex containing 39 carbon atoms, so as to show the effect of combining the metal isotope pattern with the 12C/13C pattern.  This worked using Version 1.1 of PAT for Windows in 32-bit Windows 7 and in Windows XP PCs, but crashed the PAT program in 64-bit Windows 7 No one reported the bug in version 1.1, so perhaps no one tried to use it in 64-bit Windows 7 for fragments containing more than about C17.  If you find any bugs, I should be grateful if you would tell me about them.  My email address may be found below, or at the bottom of the ReadMe web page, or in the program by clicking Help, Setup and scrolling to the bottom of the text
