Voice recording: Wav jumps (missing sections each recording)

[FireW0lf]

Hi

I downloaded KaraFun Free Version: 1.18 Build 1081 primarily to be able to record the singing

Unfortunately, on playback of the voice wav, it is missing several sections per wav, of perhaps 1/4 of a second. This of course results in choppy playback

This has been installed on 3 different machines: XP SP2, XP SP3, Vista 32

Over SATA, and IDE, freshly defragged

Over DDR and DDR2 ram

Over Realtek and C_Media sound chipsets, with the latest drivers

I'm an IT and Network Engineer, and know the machines are working and config'ed tip-top (One is a brand new Sony Vaio with a fresh clean install)

Would love this to be fixed

Any ideas? Thanks in advance
