I have just bought a new laptop that has Windows 7 64bit operating system. Downloaded PC Companion last night but when I plugged the phone into the laptop, it failed to load the drivers. Is this a known issue? I have an Xperia Neo.
Which function are you looking to perform between phone and PC? I only ask as depending on what you are trying to do you may not even require the installation of this program at this time.
Wanted to back up my contacts and transfer some music to my phone. Just tried it again and my phone was found and everything seems to be working ok.
I know its slightly off subject but something that is really starting to annoy me is that I have created folders on one of my home screens like travel, shopping and games. I have dragged apps into the folders but if I switch off my phone or plug it into my laptop, next time I look the apps have gone. Really fed up with this. Am I doing something wrong?
that doesn't sound right, try to move the apps to your SD card
settings -> applications -> manage applications -> on SD card
see if that solves your issue
for future reference
here are some methods to backup your contacs, apps, etc
Use one of these links to download the Backup & Restore app

How to install it
You need to
go to settings -> applications -> check unknown sources
download IO File Manager

download the backup & restore app, transfer it to your SD card, use OI file manager to find it -> tap on it -> install it
Contacts
just to play it safe sync your contacts w/ google if you haven't already
open your phonebook
Don't worry so much about backing up your apps
on your computer go to

SMS/MMS
if you don't want to use the backup & restore app then
Install "backup SMS" to back up your SMS and MMS to your Gmail

or your SMS use

or My Phone Explorer

Probably not. Not sure if the following workaround will help you.
Can you try this. When this happens again, can you perform an SD card Unmount on your phone itself.
Go to the phone settings menu --- Storage --> Unmount SD card.
When the card has been unmounted, remount the SD card.
Then check whether you see the apps in the folders again.
The apps are still in their folders. There is another issue which keeps occuring. When I press the grid icon to look at my apps there are gaps in the grid as I scroll through the screens. At the moment screens 1-4 have 16 apps on them. screen 5 has 7 apps on it. Screen 6 has 14, screen 7 has 14, screen 8 has 15, screen 9 has 16 and screen 10 has 5. lost count of how many times I've re-arrange these apps. 
do you have android 2.3.4?
No. I have Android 2.3.3
