slow screen refresh under windows 2000

[tedbain]

takes about 4 secs to refresh subwindows (command or browse screens) when running under win 2000 on 800Mhz pentium3. I copied program files to pentium2-166 and it refreshes in fraction of second. Runs much quicker under runtime. Have same problem on two different computers.

Can anybody help, please??

First, may I presume you're asking about a 2.x FoxPro for Windows application?

Unless you have a disk (IO) bottleneck (are the data files on a network?), it's likely your video card (chip set?) or video drivers that are the problem. Many of the older systems used "high power" video cards, and now because the newer systems have so much extra CPU power, the manufacturers are using cheap video chip sets and let the main processor do most all the work. Also, with so many OS driver possibilities, they don't seem to be spending the time or expense to optimize all of them as they did in the past (again especially for the cheaper video chip sets).

Hi
In the W2K desktop, in a plain area >>>>
right click,
click on properties,
click on 'settings' tab,
clcik on 'advanced'
click on 'troubleshooting'
slide the hardware acceleration bar down a few stops.
Now clcik OK and again OK

Now you are done. Run the programme. You must be feeling a lot more better and comfortable.

If the above did not yield what you expected, then in the settings, reduce from 32 bit true color to 16bit true color and try the same. You are sure to get far better results.
Best of luck
Hope this helps

also...

check you have SET AUTOSAVE OFF (assuming you're not relying on it to save data).

I found this made a huge difference between w2k and NT.

the more tables you have open the worse it is.

thanks for quick reply

tried ramani's steps on work machine (will try home later).... only problem my Compac deskpro EN hardware acceleration bar is locked on full speed.

colour already on 16 bit tried reducing to 256..no effect

next reduced screen size back to 640 (from 1024) with great improvement. Changed back to 1024 .. still okay. Re-started FoxPro (2.6 with patch2x).. back to square one. Changed screen size again .. no improvement this time (even at 640).

getting my it people to have a look but don't hold much hope... will get back later whatever transpires

back again...

autosave not the problem

lot of talk from my IT about old architecture which I sort of follow but couldn't repeat.

Turns out that the problem is far worse on my slave drive (removable harddisk which goes between work and home) than on C: ... Can live with using C: but a real pain.

Also found that I can do a fair bit by working under a project and having a program open (eg a simple .spr waiting for closure)

Thanks again.. can live with it for now but will keep an eye on forum
