Google Custom Search / Collapse-O-Matic issue for URLs containing hash-bang

Google Custom Search opens a popup (as it should) here (without hash-bang) but not here (with hash-bang). When I temporarily deactivate Collapse-O-Matic, Google Custom Search opens popups correctly at both those URLs. The only two plugins activated are “Google Custom Search” and “Collapse-O-Matic”. Another plugin I’m using requires URLs with hash-bang, so this is a problem for me. Would you investigate?
