This is absolutely correct, even the right fix. I put that into the distribution. Thanks a lot.

The easiest to achieve this is to define another option. Assume you have the three options

One, Two, Three

and you want to "unselect" them. So just add a fourth option like

Unspecified, One, Two, Three

so if you do not want any of the "One, Two, Three", just click on "Unspecified" and you get what you want.

gmail uses TLS (Transport Layer Security) for the mail communication, which is currently not supported by elog. 

That's strange. Normal pages are set to "pre-expire" (expiration date 1983...) which forces the browser to always load them from the server. This is necessary since someone else could have modified that page and you would look at an old page in your browser's cache. But using this, I never saw a "page expired" message. The browser simply reloads the page. Maybe if the internet connection got lost in between and the browser cannot load the page from the server, you have a problem. Attached pictures have a expiration date of +1 day. So even if you span different time zones, that should be fine. Can they try to access https://midas.psi.ch/elogs/Linux+Demo/14 and see if they get the same problem there? This is my demo setup and resides in Switzerland.

The only way to get two entries is if you submit your entries twice. The same problem exists on some credit card payment sites, which explicitly state "please be patient, don't press submit twice, don't press back". The same applies for elog. 

No, this is not implemented right now. But if nothing else helps, I can add a new option.

Not much. Since they are the only ones reporting this problem, I'm tempted to attribute this to their local configuration (browser, proxy, etc.). Have they tried different browsers on different machines?

No, this is not imlemented. But you can go to the "Find" page, and select the "Start" and "End" date with the calendar picker tool. This are a few more clicks to do, but puttting this all into the quick filter would not fit there. 

The conditional attributes work only with Options, but not with MOptions as written in the documentation. I tried your set-up with Options and it worked ok. If you attribute Phase is non-exclusive, meaning it could be Manufacture and Testing at the same time, then you have to play some tricks with an additional attribute like

Attributes = Author, Topic Date, ..., Duration, Transport

MOptions Phase = Design, Manufacture, Testing, Results, Transport

Options Transport = Yes{2}, No{1}

{1} Show Attributes Edit = ...

{2} Show Attributes Edit = ...

Using the Windows event log won't help much. I guess in your case elogd is driven into some kind of endless loop (does the CPU go to 100%???). There are only two possibilities to tackle this:

1) You find a way to reliably reproduce this problem, tell me how to do this. When I can reproduce it here, I can fix it easily.

2) You do debugging yourself. Under Linux this is simple, since you have debuggers on most systems. Under Windows however, you first have to install the Visual C++ development environment. I believe there is a free version (Express?) which you can use. You then run elogd under the debugger, and when it hangs you investigate where. This needs some basic knowledge about C++ development and I'm not sure if you have this, but maybe you can find someone around you who does.
