Quartus II Crashes

[Altera_Forum]

Hello, 

 I am running Quartus II 32-bit Version 12.0 Build 263 08/02/2012 Web Edition,  with Service Pack Installed: 2 on Windows 7.  I am using schematic design entry in the Block Editor. I create a new design and compile it without problems. I then make a simple edit, for example re-naming a pin, save the file, and attempt to compile again, and it crashes.  The crash report window says:  ------- start paste ------  Internal Error: Sub-system: DBMUI, File: /quartus/db/dbmui/dbmui_manager.cpp, Line: 1152 Attempt made to free all hierarchy databases but the following callers are still accessing it: GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_hdb_iname, GED_VIEW::get_sld_hdb_iname, GEDQ_VIEW::get_sld_h Stack Trace:  0x61c9: DBMUI_MANAGER::close_hdb_all_cap_inst + 0x109 (DB_DBMUI)  0x6ee7: DBMUI_MANAGER::flow_has_started + 0x27 (DB_DBMUI)  .... lots more lines like above .... End-trace Quartus II 32-bit Version 12.0 Build 263 08/02/2012 SJ Web Edition Service Pack Installed: 2  ------- end paste -------  When I re-launch Quartus and compile the edited .bdf file there is no problem. The above behaviour happens consistently, every time.  Am I doing something wrong, or is my installation incorrect, or is it a bug? If the latter, how do I report it?  Thanks for any help, Ken.
