I get this warning message when Maestro starts. What do I do about it?

X Error: BadAlloc (insufficient resources for operation) 11
Extension: 147 (Uknown extension)
Minor opcode: 3 (Unknown request)
Resource id: 0xa00473
X Error: GLXBadContext 148
Extension: 147 (Uknown extension)
Minor opcode: 6 (Unknown request)
Resource id: 0xa00475
X Error: GLXBadContext 148
Extension: 147 (Uknown extension)
Minor opcode: 5 (Unknown request)
Resource id: 0xa00475
QGLContext::makeCurrent(): Failed.

At times, these messages appear on machines that do not have hardware-accelerated OpenGL support. They seem to be harmless, as seen till now, so should not cause any problems. They can typically be suppressed if Maestro is run using the '-SGL' flag i.e. in software OpenGL mode:

$SCHRODINGER/maestro -SGL

If you use this mode, Maestro response can be slow for large structures. A better solution is to purchase a graphics card with hardware-accelerated OpenGL.
