9. Known Problems


9.1 Virtual Memory

Some testers have had problems with frequent Type 2 errors if VM is enabled. Others have experienced no problems. I am endeavouring to find the real cause of this, but it appears to be caused by RealBASIC and is probably beyond my control. By all means try Monica with VM enabled, but if you get Type whatever errors then disable VM.

9.2 Other Problems

If it doesn't function in the expected fashion please note any error messages that occur and, if possible, take a screenshot of Monica's window. Please then email me, describing as fully as possible what was going on. I would really appreciate your taking the time to do this!

9.3 Funnies

1. There are some ftp servers out there that talk nonsense! Some servers say they are restarting but don't.

2. Comms errors DO occur which can result in corrupt files. I have seen this on certain http servers more than once, where files larger than expected have been received.

3. There are some http servers that talk nonsense too! One server gives a 206 ( restarting with partial content ) but starts with whole file. I have forced Monica to delete any local file and restart if the server says it is restarting but does not give a content length.

4. Some http servers insist on sending one byte if you attempt to restart but already have the complete file. These servers miscalculate the byte range for sending. I have kludged around this problem.

5. Proxy server funny. Some proxy servers, if they have an incomplete part of a file in their cache, will transmit ONLY that part even if you request the whole file. I have set Monica to request the proxy never to use its cache, but Proxies seem a law unto themselves sometimes!
