At first: I 've no quick solution for that. But we use this bastard still, too

So here comes a big bag full of questions and tip...
Anything to see in the RR logfiles?
What might have happened before sunday? Might the PCs have 'suffered' from any updates by automatic software distribution or during network-logon like patches, new registry-settings (policies) ?
Is there any other software on these machines that shows unusual behaviour?
Try to find out why it freezes up. And for how long, perhaps itself or a called driver waits until a timeout... be patient for 15mins or so...
If possible, use Filemon (
to see what the program tried to do before it falls asleep.
Some time ago I had a really bad day 'cause the local sqlnet.ora and tnsnames.ora where replaced by new ones which forced the use of an oracle names server...
And again when they distributed the Oracle9-client. It does not support connecting to Oracle7 (ACD 7.x,8.x), it works up to Oracle8-client...
Check DB-connectivity:
- tnsping to your acd, login using sql-plus.
- ODBC, try accessing the ACD with odbc-test, ms-access, ms-query or something else.
Remember, RR is old 16bit-stuff, the ODBC-config could be corrupt even if you can use the programs to test the connection. If you installed the Oracle7-client provided by Aspect there should be a 16-Bit ODBC-admin in the folder of RR in the start-menu, and an ODBC-test-program, too. Or look for the binaries in the RR program-folder and oracle-client.
I hope you don't need to fiddle around with ODBC-manager and drivers. Their configuration is stored in the registry and in odbc ini-files in the windows directory. Best case is when you have a clean installed base system
Last resorts: deinstall RR, kill his files in c:\cvr or where it was installed, delete its ini-files from the windows directory (look for crw.ini,cvr.ini, crd.ini, runner.ini(?), I could look for exact filenames at work tomorrow).
Then install the bastard again. To make shure the mdb is ok, don't use your backups. At first just try to run one of the example-reports already defined in the fresh installed mdb provided by RR.
Perhaps one of the components/dlls of the system have been updated by another piece of software or are corrupt. For example msvcrt.dll is often kept in the directory of an application, but sometimes an installer updates the version in \winnt\system32. ODBC-installation, jet-engine, libraries for common controls/dialogs are other candidates, too.
As I said, no quick solution. But I hope it helps to find the solution

Let us know what's going on...
bye,
