Yesterday, I had to fix another Windows XP computer infested with Spyware and Viruses. Thanksfully I cleaned it up as usual using standard combination of Malware Bytes + Little Registry Cleaner and Avira. The PC haven't been updated recently and running still Windows XP SP2, thus to make Avira running I had to install SP3 as Avira nowdays depends on Win SP3. After clean up it worked much better, though it is not 100% sure if some kind of malicious software is still not on PC.
After all seemed fine on this Russian Windows XP, there was one thing still problematic – Skype. For some weird reason whenever user from Skype contact list is messaged, it was impossible to send the message with Enter key. I tried checking if all seems fine in Keyboard Settings and Regional Settings in Windows Control Center, cause XP version was with Russian Language Pack and I suspected the Language Pack might mess up something in how Keyboard keys are mapped but all seemed fine there. One important note to make here is PC is running on old hardware and had an old standard PS/2 Keyboard detected as PS/2 – 101 – 102 keys standard keyboard. I tried re-installing the keyboard driver, trying to auto-detect however driver detected for this keyboard seemed to be latest issued for PS/2 Keyboards from Microsoft so after update Skype can't send message bug was still present and respectively the only way to communicate with people from contact list was to Call the person and speak. I researched online on the problem and found a multitude of users complaining to face the same Skype messaging – Enter key not working, unfortunately noone online seemed to have found a solution. I've seen some suggestions to use Skype settings to re-map Enter key but on this Skype 184.108.40.206 the option to remap how Enter key reacts wasn't present. Thus I decided to try to downgrade Skype 6 to Skype 5 here is a mirror of Skype 5 -and try if this helps. After Uninstalling Skype 6 and installing Skype 5 – enter key started working again so mission accomplished If you happen to have the annoying Enter key not working in skype bug just downgrade to any below version to 6 and all will be fine. Drop me a comment if you experience the same bug with Win and Skype version.
Finally, be sure not to upgrade further Skype to avoid problems. Last but not least, there is even some advantages in older skype releases, the interface is simpler – making work with skype easier.
