Bug ID: 43063
           Summary: MetaTrader 4 has no internet connection
           Product: Wine-staging
           Version: 2.8
          Hardware: x86-64
                OS: Linux

MT4 startup log

After starting MetaTrader 4 the message 'Common error' is shown in connection
status (bottom right corner of the window).

All charts shows a big message 'Waiting for update'. No graphics/data is shown
on charts.

MetaTrader 4 was working fine until wine-staging 2.7.
This problem is occurring only in wine-staging 2.8.

Downgrading wine-staging to version 2.7 "fixes" the problem.
Using regular wine version _2.8_ also "fixes" it.

So it seems to be a regression of wine-staging 2.8. The bug also seems to be
_not_ present in the regular wine version.

System information:
OS: Arch Linux x86_64
wine: 2.8 staging

Notes:
1) MetaQuotes do not provide the (unbranded) MT4 download in their website
anymore. Now there are only broker-branded versions and the links the can found
at broker websites. For example, FxPro MT4 can be downloaded from:
https://download.mql5.com/cdn/web/fxpro.financial.services/mt4/fxprocom4setu...

2) MT4 seems to need gnutls for proper installation (dependency lib32-gnutls is
needed for install).

3) Using comctl32 from winetricks fixes tooltips problems in charts.
