OALogin "Low on memory" error when logging in samples or after reload on TOF MS instruments - WKB3424

SYMPTOMS

• Logging in samples / selecting the method in OALogin on a TOF MS gives system low on memory error
• Also seen after reloading OALogin and replacing the OALogin.pro file 
• OpenLynx methods (*.olp) not visible in the drop-down box

ENVIRONMENT

• MassLynx
• OpenLynx, OALogin, OA Manager
• Any TOF based MS instrument running with MassLynx
• Xevo QTOF MS, Xevo G2-TOF, Xevo G2-QTOF, Xevo G2-S TOF, Xevo G2-S QTOF, Xevo G2-XS, Synapt, Synapt G2, Synapt G2 S, Synapt G2 Si

CAUSE

SpecProc is used for the instrument installation and has many *.olp files associated with the program.  
OpenLynx uses *.olp method files stored in C:\MassLynx.
If the SpecProc files are left in the MassLynx directory then OpenLynx searches all these files during sample log in causing memory issues.

FIX or WORKAROUND

1. Move all the .olp files that are not OpenLynx methods to a folder that is not C:\MassLynx.
2. Move all the SpecProc based .olp files into the C:\MassLynx\Commission.PRO\
