Too fast update with keepuptodate

Hi!

First of all I would like to thank the author, winscp is just awesome!

I'm running version 3.8.1 and is using the keepuptodate feature from a script to upload files from a directory that is updated every minute. It however jams a couple of times a week.

I run it from sync.bat:
@echo off
: START
"C:\Program Files\WinSCP3\WinSCP3.com" /script=uploaderscript.txt
GOTO START

using uploaderscript.txt:
# Automatically answer all prompts negatively not to stall the script on errors
option batch on

# Disable overwrite confirmations that conflict with the previous
option confirm off

# Connect
open user@domain.tld

# Force binary mode transfer
option transfer binary

# Keep remote directory updated
keepuptodate D:\Sync\Datafiles /home/user/data

# Disconnect
close

# Exit WinSCP
exit

which outputs:
batch        on
confirm      off
Initialisation...
Searching for host...
Connecting to host...
Authenticating...
Using username "user".
Authenticating with public key "userkey" from agent.
Authenticated.
Starting the session...
Reading remote directory...
Session started.
Active session: [1] user@domain.tld
transfer     binary
Watching for changes, press Ctrl-C to abort...
Scanning 'D:\Sync\Datafiles' for subdirectories...
Watching for changes in 1 directories...
Change in 'D:\Sync\Datafiles' detected.
Local 'D:\Sync\Datafiles' => Remote '/home/user/data'
D:\...\file1.bin   |          0 kB |    0,3 kB/s | binary | 100%
D:\...\file2.bin   |          0 kB |    0,3 kB/s | binary | 100%
Change in 'D:\Sync\Datafiles' detected.
Change in 'D:\Sync\Datafiles' detected.
Local 'D:\Sync\Datafiles' => Remote '/home/user/data'
D:\...\file1.bin   |          0 kB |    0,3 kB/s | binary | 100%
D:\...\file2.bin   |          0 kB |    0,3 kB/s | binary | 100%
Change in 'D:\Sync\Datafiles' detected.

but then at some point it jams and is not restarted by the goto-loop until I change the window focus to another application! This is the last output before it hangs:
Change in 'D:\Sync\Datafiles' detected.
Local 'D:\Sync\Datafiles' => Remote '/home/user/data'
D:\...\file1.bin   |          0 kB |    0,0 kB/s | binary |   0%
Can't open file 'D:\Sync\Datafiles\file1.bin'.
(A)bort, (R)etry, (S)kip, Ski(p) all: Abort
Retry or possible skip would be the appropriate action here...

I think the problem is that it's too fast, it would need to wait a fiew seconds after a change is detected and then do the upload. The changing of the delay seems to be undocumented but existing? According to the History for 3.8 beta:
Synchronization enhanced: Synchronization delay for function Keep Remote Directory Up To Date is configurable (only directly in configuration files).

Have any idea why?

You can change the delay in registry:
REGEDIT4

[HKEY_CURRENT_USER\Software\Martin Prikryl\WinSCP 2\Configuration\Interface]
"KeepUpToDateChangeDelay"=dword:000001f4

I renamed my .bat to .cmd and it has not jammed since then. (Running for more than 6 weeks!)
